Glass Fiber Reinforced Concrete (GFRC)


Product Data

Exterior Cornices, columns, decorative exterior wall panels and limitless specialized decorative shape applications.


Design

Shop drawings are submitted for verification of profiles, dimensions, and surrounding construction of GFRC units. Some site cutting and/or grinding of parts may be required to suit job conditions. Field shimming may be required. Connection and attachment details are indicated on the shop drawings. It is the responsibility of the installer to follow the shop drawings and coordinate field inspections as required. Installer should verify job conditions and make installation adjustments accordingly. Installer shall get approval from GFRC engineers for deviations from the connection/attachment details indicated in the shop drawings.

Fabrications

Mix - GFRC is batched and blended in accordance with industry standards using the specified mix design.
Application - GFRC mixture is sprayed and/or hand laid into molds designed to match the shape and dimensions shown on the approved shop drawings. The nominal shell thickness is 3/4”.

Finish – GFRC can be produced in a variety of finishes , some of the most common would be a acid or sandblasted finish with an integral color or with colored aggregates that produce a multi colored finish. You can also reproduce stone finishes such as limestone, Granite and sandstone. GFRC can also be finished to simulate a terra cotta finish or cast smooth to receive a wide variety of paints and coatings.


Delivery

GFRC units are created or palletized at the plant. Created units are delivered to the jobsite via truck.


Storage

Store crated GFRC products on a level surface protected from weathering and damage. Do not unpack crates until immediately prior to installation.


Handling

Use special care to prevent damage to material surface; do not allow acidic materials to come in contact with surface, as degradation and discoloration can occur.
